What reviewers think

Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.

What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

Brand highlights

Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:

  • Their amplifiers often feature point-to-point wiring, a more labor-intensive and traditionally hifi construction method, reflecting a commitment to quality craftsmanship.
  • Line Magnetic's SET (Single-Ended Triode) amplifiers deliver a signature free-flowing soundstage, often described as exceptionally natural, emotionally engaging, and vividly 3D.
  • They offer models with adjustable negative feedback, a rare feature in tube amplifiers that allows users to fine-tune the sound to their preference or speaker characteristics, offering greater flexibility in system matching.

Anni

Reviews

Anni is our first-ever desktop integrated amplifier. Capable of driving both headphones and compact loudspeakers, Anni benefits from the company's proprietary ULTIMA circuit topology and is perfectly positioned to exploit the full potential of today's high-performance headphones, desktop monitors and high-resolution audio sources.

The new Anni desktop integrated amplifier forms part of the Qutest range and seamlessly complements the resolving abilities of the multi-award-winning Qutest standalone DAC and Huei phono stage. As a system, the Qutest components provide an unrivalled desktop audio solution, offering class-leading digital and analogue technologies for the modern music lover. The company's compact QSS (Qutest Stand System) modular equipment rack provides the perfect support, too.

Anni offers the recently announced dual-feed-forward error-correction circuit topology whether using headphones or compact loudspeakers. Anni's advanced technology allows it to drive any headphone load, error-monitored and compensated amplification at all times.

Benefitting from both 3.5 mm headphone outputs and ¼-inch (6.35 mm) outputs, so two can listen simultaneously, plus 4 mm banana-type loudspeaker outputs, Anni delivers 10 watts of quality ULTIMA amplification, controlled by a fascia-mounted volume control that also doubles as an input selector switch for Anni's two line-level inputs. A two-stage gain control for loudspeakers provides additional flexibility with a wide range of desktop monitors.

Chord Electronics designs and manufactures all their products in Great Britain, setting themselves apart by using proprietary FPGA technology instead of off-the-shelf DAC chips found in most competitors' products. Their DACs and portable audio devices, featuring distinctive color-changing buttons and portholes, deliver studio-grade performance through unique technologies like the Watts Transient Aligned filter, which provides more natural and detailed sound reproduction.

Expand Details

Product Strengths

  • Joyful sound signature with detailed output
  • Can power a wide range of headphones, due to Ultima technology
  • Compact design, stacks perfectly with the Qutest and Huei
  • Employs trickle-down Ultima technology to allow delivery of enormous peak current outputs
  • Solid build quality using CNC-milled aluminum casework and good heat dissipation
  • Connectivity options include headphone and speaker outputs

Product Considerations

  • No gain switch for the headphone output
  • Default gain level a bit high for sensitive IEMs
  • More power limitations with speakers than headphones—best for smaller, efficient speakers or nearfield listening
  • Runs hot, requiring good ventilation
  • The volume control feels a little wobbly and might be difficult to use in a very precise way, and there is some channel imbalance at very low volumes

Comparisons (according to reviewers)

  • Qutest/Anni pairing justifies its price premium thanks to a more composed and insightful presentation that offers notably more low-end authority, dynamic punch and tonal richness
  • Cyrus ONE HD is plusher, showing that Anni has strong niche appeal
  • The iFi xDSD Gryphon has digital inputs and built-in DAC, while Anni can power speakers

Takeaway: The Chord Electronics Anni is a compact and well-built amplifier that delivers a joyful and detailed sound, making it a great addition to a desktop setup for headphone and nearfield speaker listening. Its use of trickle-down Ultima technology ensures high-quality performance in a small package, and its ability to stack with other Chord devices makes it a good choice for those already invested in the ecosystem.

  • The volume dial makes subtle volume adjustments difficult, going from quiet to loud too quickly
  • Uses DIN connectors for the line-level analogue inputs, requiring adaptors for RCA connections, but no DIN cable is included
  • On powering up, a thump is followed by a plop when switching in from standby

Comparisons (according to reviewers)

  • Vs Naim Nait XS 3: Nait 50 is punchier, cleaner, more precise, and lively
  • Vs Naim Uniti Atom: NAIT 50 feels more old school Naim

Takeaway: The Naim Nait 50 offers a fun and engaging listening experience with a retro design that will fit in any listening room, either old or new. It can serve as a workhorse in a reference system and headphone rig.
